co-star in Europe

I live in Europe and I've just received my co-star, via a friend from US, and I have some questions.
1. As far as I noticed the time is set according to the ZIP code entered into the settings. Is there a way to change the clock to any other timezone?
2. What about other sat/cable boxes, I'm talking about those boxes out there which are not in the list co-star knows. There are lots of dreamboxes and other enigma2 powered boxes, which are way more better than those listed by co-star.
3. co-star knows my TV (LG LH series), but won't do more than turn ON/OFF, vol UP/DOWN, mute. Is there a way to teach the remote? Same question for sat boxes. Is somewhere a list containing codesets for remote controls?
4. Is it possible to access the default android settings, not the co-star forced one?
